Keeping foreskin forward
I’m uncut and just realized my past problems with pumping such as fast restriction of blood supply and rapid edema (donut effect) might be caused by my foreskin that peels back while in the tube.
My foreskin tends to peel back while I’m slowly increasing the pressure. Always end up cutting blood supply to the glans causing it to slowly turn blue-black from the coronal ridges and upwards. The maximum I’ll can withstand is 5 minutes before releasing the pressure. When I pump again, my sessions are limited by massive edema (donut effect) as again the foreskin constricts exactly the point where lymph fluid from the glans enters the shaft.
However last night, my foreskin already pretty pumped from earlier sessions stayed put surrounding my glans. And at the end of 15 minutes of 6 mmHg pump, I noticed my glans never turned blue and foreskin swelling was very very minimal.
I wonder if there’s a way to keep the foreskin forward for those uncut while pumping, etc prevent it from peeling back.
